Buyers typically pay $5,000-$15,000 to install a new central AC and full ductwork replacement; the exact cost depends on system size, duct complexity, and regional labor rates. This article breaks down typical price ranges, per-unit rates, and the main cost drivers so homeowners can budget accurately for the cost of new AC and ductwork.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| AC Unit Only (3-ton) | $1,800 | $3,500 | $6,000 | Includes condenser and coil; mid SEER |
| Ductwork (Full Replace, 1,500 sq ft) | $2,000 | $5,500 | $10,000 | Sheet metal, average layout |
| Combined Install (Typical 1-2 story) | $5,000 | $10,000 | $18,000 | Includes labor, permits, basic registers |
| Mini-split Option (per zone) | $1,500 | $3,200 | $6,000 | Alternative to duct replacement |

Total Installed Price For New AC With Ductwork In A Typical Home
Expect total installed prices of $5,000-$15,000 for most U.S. homes, with $10,000 as a useful midpoint for budgeting.
Typical totals assume a 1,200–2,000 sq ft house, a 2.5–3.5 ton central AC, full sheet-metal duct replacement, and standard attic or crawlspace access. Low-end jobs use basic 13–14 SEER units and partial duct sealing; high-end jobs use 16–20+ SEER units, custom sheet-metal runs, and significant structural work.
Assumptions: Midwest labor rates, 1-story or 2-story with attic access, standard equipment, no major drywall repairs.
How Materials, Labor, Equipment And Disposal Add Up
Materials and labor are the largest line items; together they typically account for 70–85% of the final price.
| Cost Component | Low | Average | High |
|---|---|---|---|
| Materials (unit, ducts, registers) | $1,500 | $4,000 | $9,000 |
| Labor (installation, duct work) | $1,200 | $3,500 | $6,500 |
| Equipment & Tools | $200 | $500 | $1,200 |
| Delivery / Disposal | $150 | $400 | $1,000 |
| Permits & Inspections | $50 | $300 | $1,000 |
Typical labor: 10–40 hours depending on duct complexity; typical hourly trade rate: $75-$125 per hour.

How System Size, Duct Length, And SEER Change The Price
Increasing system tonnage by 1 ton typically raises the unit cost by $800-$1,800; every SEER jump (e.g., 14→16) adds $400-$1,200.
Key numeric drivers: house square footage determines tonnage (approx. 1 ton per 400–600 sq ft). Duct linear footage over 150 linear ft often adds $1,000-$3,500 due to materials and labor. Long runs or many bends increase labor hours and leakage risk.
Thresholds to watch: 2.5–3.5 ton (common); >200 linear ft of ducts triggers higher bracket; SEER 16+ moves into premium pricing.
Practical Ways To Lower New AC And Ductwork Price
Controlling scope and choosing targeted repairs over full replacement can cut costs by 20–40% in many homes.
- Replace only damaged duct runs and seal/insulate the rest rather than full replacement.
- Choose a mid-efficiency unit (14–16 SEER) instead of top-tier models to save $1,000+ upfront.
- Schedule work in shoulder seasons (spring or fall) to avoid peak contractor premiums.
- Provide clear access and do minor prep (remove ceiling fixtures, clear attic) to reduce demo time.

Price Differences Between Regions And Climate Zones
Regional labor rates and climate needs change price by roughly ±20–40% across the U.S.
Examples: Northeast and West Coast urban areas typically add 15–40% to labor and permit costs compared to Midwest rural rates. Hot-humid Southeast may require larger capacity or dehumidification, increasing equipment costs by $500-$2,000. Remote or rural jobs may add delivery/disposal charges of $200-$800.

Estimate deltas: Midwest baseline, +15–25% urban premium, +20–40% high-cost coastal regions.

Concrete quotes help translate ranges into real expectations for specific home types.
| Scenario | Specs | Labor Hours | Total |
|---|---|---|---|
| Starter Home | 1,200 sq ft, 2.5 ton, partial duct repair | 12 | $5,200-$6,800 |
| Average Suburban | 1,800 sq ft, 3.5 ton, full sheet-metal ducts | 24 | $9,000-$12,500 |
| High-End Retrofit | 2,500 sq ft, 4.5 ton, custom ducts, 18 SEER | 36 | $14,000-$20,000+ |
Permit, Removal, And Add-on Fees To Expect
Permits, old system removal, and code-related upgrades commonly add $300-$2,000 to the invoice.
Typical charges: permit fees $50-$800, refrigerant handling or reclaim fees $100-$400, old system haul-away $75-$300, and required code upgrades (e.g., new disconnects, condensate pumps, HVAC electrical) $200-$1,500. Factor contingency of 5–15% for unforeseen repairs found during installation.
Assumptions: municipal permit requirements, licensed HVAC techs, normal access.
